Google is facing increasing legal challenges as a U.S. federal judge ruled the company holds illegal monopolies in the online advertising market. The ruling comes after a September trial in Alexandria, Virginia, and marks the second major antitrust blow against Google in under a year. Earlier, a judge concluded that Google monopolizes the internet search market, a ruling considered one of the most significant antitrust decisions in tech since the Microsoft case more than two decades ago.
This ongoing legal battle has put Google in a vulnerable position as it seeks to defend its core business in court while also facing new competition fueled by the rise of generative artificial intelligence, particularly from OpenAI’s ChatGPT, which offers users alternative ways to search for information. Meanwhile, Google’s revenue growth has slowed, and economic concerns linked to new tariffs imposed by the U.S. have raised the possibility of decreased ad spending.
The latest ruling, made by U.S. District Judge Leonie Brinkema, found that Google’s control over two major components of the advertising technology market—the publisher ad server market and ad exchange market—was anticompetitive. However, the judge dismissed one part of the case related to general display advertising, noting that the government had failed to prove that Google’s acquisitions, such as DoubleClick and Admeld, were anticompetitive.
Google, in response, stated that it disagreed with the decision and planned to appeal, particularly regarding its publisher tools, which it argues provide affordable and effective solutions for advertisers. The Justice Department, however, has claimed the ruling marks a key victory in its effort to prevent Google from dominating the digital advertising space.
The ruling could pave the way for regulators to force Google to divest portions of its ad-tech business, potentially opening up opportunities for competitors like Amazon to gain market share. While Google’s search monopoly case is still pending, its ad business remains its most critical revenue driver. Experts suggest that a breakup of the ad division could have a more significant financial impact on the company than the search case.
As the legal battles continue, Google’s stock has taken a hit, down 20% this year. The company’s ability to navigate these legal challenges and adapt to a rapidly changing tech landscape will be crucial in determining its future trajectory.
